abrogate

Abrogate is a transitive verb meaning to abolish, repeal, or nullify something, especially a law, treaty, or formal agreement, by authoritative action. In legal and political contexts, abrogation signifies the formal ending of a binding obligation and is typically deliberate and explicit, originating from the powers of a legislature, executive, or international actors to terminate existing rules or commitments.

In contrast with repeal, abrogation often emphasizes final nullification rather than mere revocation, though the terms can be used interchangeably in some contexts. Abrogation may be permanent or temporary depending on the instrument or authority involved, and it may occur with or without a replacement rule or agreement.

Etymology: abrogate comes from Latin abrogare, from ab- “away” + rogare “to ask, propose,” originally conveying the sense of cancelling by formal act. The noun form is abrogation.

Usage notes: Abrogate is a formal term more common in constitutional, treaty, or organizational contexts than in everyday speech. It connotes sovereignty or high-level authority and is typically associated with official, state, or institutional action.

Examples: The constitution was abrogated following a coup. The parties agreed to abrogate the treaty and negotiate a new one. The rule was abrogated by the board’s decision.
